DUMPINGICARn Specification of Letters Patent. r tested May 29,1906.

Application filed January 29, 1906. Serial No. ZQSASL To all whom it may concern:

Be it known that I, J OHN KNITTEL, a resident of Allegheny, in the county of Hegheny and State of Pennsylvania, have invented certain new and useful Improvements in Dumping-Cars; and I do hereby. declare the following to be a full, clear, and exact description of the invention, such as v'ill enable others skilledhin the art to which it ap pertains to make an use the same.

My invention relates to improvements in duiiiping-cars, the object of the invention l dinal shaft 26, connecte being to provide an improved dumping-car in which a single operator can tilt the car body. to any angle to partially or entirely dump the contents thereof and in which the body will be locked against movement at any and all positions. i

A further object is to provide improved means for releasing the body to permit it to return to normal position and provide abrake to govern the return movement of the body. I'Vithtliese and other objects in view the invention coiisistsin certain novel features of construction and combinations and arrangements of parts, as will be more fully liereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation, illustrating my improvements. 2 is an end view, and Figs. 3 and 4 are enlarged views of details of construction'.

1 represents a car-platform supported on wheeled trucks 2 and having uprights or standards 3 secured thereon near'its respective ends. y 4 represents my improved car-body,which is preferably of substantially 'semicylindrical form, preferably flared at its top an provided with concentric trunnions 5 at its ends supported in bearings at the'top of stand.- ards 3. Curved worm-racks 6 are the car-body 4: at its respective ends and are normally in mesh with worms 7, the latter secured upon shafts 8,: mounted in eccentric bearings 9, and said bearings are pro vided with arms .10. The arms 10 are connected by links 11 with the arms 12 of crankshafts, and. other arms 13 of said crankshafts are connected together by a link 14 and to alever 15' by a link 16, so thaftwhen said lever is moved the eccentric bearings will be turned to move the worms 7; into or out of mesh with racks 6. Lever 15 is proa detent 1-7 to engage a notche located on aegment 18 and lock the lever in anyposiion. 1 1

On astandard 3 at one end of the car an approximately vertical shaft 19 is supporte and provided at its upper end with a wheel 20 to turn the same. i This shaft-- '19 has a beveled gear 21 at its lower end'mesh iiig with a similar gear 21 21 and the latter carried a pinion 22 at one end meshing witha gear 23 on a'shaft 8; T he other end of thisshaft 8 has a beveled gear24 meshing with a similar (gear 25 on a longitub and 28 with the other shaft 8, so that both shafts will hand-wheel 20 is turned. By turning shafts 8 worms 7 meshing with racks 6, will cause 4 to tilt, and the contents of the bodycan be entirely or partially dumped as desired, the worms serving to lock the body at any and all positions. To permit a rapi return oftlie body to its normal position, lever 15 may be operated to throw the worms out. of mesh with racks 6, when the-body will swing back to normal position by gravity, and to prevent a too rapid movement of the body a brake 29 is provided to engage the body and restrict its momentum by 'ic tional contact. This brake is controlled by a lever 30 at one end of the car, and the entire operating mechanism is therefore located at one end of the car in easy reach of an operator, who, single-handed, can operate the car. Slight changes might be made in the general form and ,arangement of the parts described without departing from my invention, andhence I would have it understood that I do not restrict myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully describ ed my invention, what I claim as new, and desire to secure by Letters ?atent, is

1. Ina dumping-car, the combination with a transverselycurved body, having a curve closed bottom, and meansfor pivotally supporting'the same,.of a curved directly to said curved bottom 0 and means-under the body engaging for tilting said body.

2. Iii a dumping-car, the combinationwith a pivotally-su ported body and a series 0 worm-racks t ereon,

racks,- operating means for each rack, and

the rack on a cross-shaft.

be turned simultaneously when d- 60. handa beveled gears 27 r the body 1 1c worms engaging said.

' means for moving the operating means into and out of engagement with the rack.

4. In a dumping-car, the combination with a pivotally-supported body, and a series of racks thereon, of a series perating means for the racks, and means for moving all of said operating means, simultaneously into orout of engagement with the racks.

5. Ina dumping-ear, the combinationwith a pivotally supported body and a series of worm-racks secured thereto, of Worms for actuating-said racks to turn the body and means for raising said worms into mesh with I said racks or lowering them therefrom.

6. In a dumping-car, the combination with a pivota'lly-s'upported body, of actuating means for tilting the body, means for throwing said actuatin means out of gear, whereby the body will be permitted b gravity to return'to its normal position, an a brake for controllin such return movement.'

.2'. Ina. um ing-car, the combination of a semicylindrica car-body pivotall supported at its ends, worm-racks aroun the body, worms meshing with the racks, means for turning the;worms, and means for movin thewor ms out of-mesh with the racks and into mesh therewith; 1

8. In adumping-car, the combination of a semicylindrical bodyspivotall supported at its ends, worm-rac 'aroun the body at both ends, worms meshing with the racks,-

shafts supporting the worms, eccentric bearings for said shafts, means for turning the shafts simultaneously, and means for turning the eccentric bearin into or out of mesh with the racks.

9. In a dum ing-car, the combination of a semicylindricafbod pivotally supported at its ends, worm-rachs dn' the bo y, worms to move the worms meshing with the racks, means for turning ends of the body su ported in the standards,

a of worm-racks on t e body, worms meshing therewith, means at one end of the car to turn the worms, a lever at the same end of the carto throw the worms out of mesh with the racks, and a brake-lever at this same end of the car to controlthe momentum of the body in its return movement.

In testimony whereof I have signed thisspecification in the presence of two subscribmg witnesses.

JOHN KNITTEL.
